MILK-BOILER.

Specicaton of Letters Patent.

Patent-eu oie-t. a, 1921.

Application filed March 31, 1921. Serial No. 457,371.

Y 1o all fw homz't may cm1 cern Be it known that l. Josnrn SLoi-zonii, a citizen of the United States of America. residing at Charleroi. in the county7 of Tashington and State of Pennsylvania, have invented certain new and useful lmprovements in Milk-Boilers7 of which the following is a specification.

his invention relates to certain new and useful improvements in milk boilers wherein provision is made for the reception and cooling of the overflow from the main or bciling compartment or receptacle of the device.

The object is to simplify and improve devices of this character and to this end the invention consists in the novel form, combination and arrangement of parts hereinafter described and shown in the accompanying drawings and claimed.

ln the drawings forming apart of this specification, and in which like referenc characters designate corresponding parts throughout the several views,

Figure l is a central vertical sectional view of one form of milk boiler constructed in accordance with the present invention,

Fig. 2 is a top plan view thereof partly broken away,

Fig. 3 is a side elevational view of the same, and

Fig. s is a Yfragmentary view in horizontal section along line lV-FV of Fig. 3.

Referring more in detail to the several views. and particularly to the form of the invention shown in Figs. l to a inclusive, the present milk boiler preferably comprises a central main receptacle 5 havingan annular relatively wide base ange 6 coextensive with the bottom wall thereof whereby the boiler is effectively supported upon a stove against tilting, the receptacle 5 being surrounded by an annular trough-shaped receptacle 7 which has its inner wall attached to the receptacle 5 as at 8 at the upper end of said wall and the upper end of the receptacle 57 the inner wall 9 of the trough-shaped receptacle being of downwardly Haring form so as to leave a space between the two recep-` tacles. The walls of the receptacle 7 are connected by a series of spaced upwardly and outwardly inclined tubes l0 which communicate with openings insaid walls whereby a passage is presented for permitting the air to pass from the space between the two receptacles to a point beyond the outer wall of the receptacle 7 so as to cool said tubes lO and consequent-ly cool the milk which surrounds the latter and which has over-flowed into the outer receptacle from the main receptacle 5 by excessive boiling. The inclined tubes 10 are also preferably interconnected by means of a series of curved tubular sections or pipes ll so as to increase the coolingsurface.` the tubes l0 and l1 being disposed beneath the upper edges of the receptacles as clearly shown in Figs. l and 2 and the upper edge of the outer wall of the trough-shaped receptacle 7 being slightly higher than the inner wall thereof and the wall of the main receptacle 5. A suitable handle l2 may be attached to the troughshaped receptacle 7 for an obvious purpose. rhe bottom of the trough-shaped receptacle 7 may be rigidly connected with the main receptacle 5 at a suitable distance above the bottom of the latter by means of radial webs 13 so as to provide a more rigid and durable construction.

In operation, the milk is placed within the main-receptacle 5 and should the same boil over, it will pass into the trough-shaped receptacle 7 and by contacting the tubes l0 and 11. the milk will be slightly cooled for preventing further overflowing of the milk from said trough-shaped receptacle, the tubes being cooled by the circulation of air therethrough.

It is believed that the construction and operation as well as the advantages of the present invention will be readily understood and appreciated by those skilled in the art.

Minor changes may be made without departing from the spirit and scope of the invention as claimed.

lVliat is claimed as new is:

A milk boiler comprising a. central main receptacle having a bottom wall, means including a side and a bottom wall forming an overflow chamber of annular form about the main receptacle with the bottom of the overflow chamber placed above the bottom of the main receptacle, said side wall heilig eX- tended above the side wall of the main receptacle and said main receptacle being provided with an annular relatively wide bottom lianged coextensive with the bottom thereof, said overflow chamber also including an inner wall of downwardly flaring form connected at its upper edge to the upper edge of the side Wall of the main recepvdng intercommunicaton between Said ra taole and spaced from the lutter and radial dial tubes.
